Why do you effectively ignore those problems and focus solely on IQ and schizophrenia?
No answer?
I don’t think that studies have ever proven a connection with decreased IQ
That was indicated only in those who used during adolescence; has any such study even been done for alcohol?
and schizophrenia from alcohol.
You are asking for defacto approval of drugs by the FDA that have shown that at least 2% of those who use the drugs develop schizophrenia with heavy use.
No, what's been shown is a correlation between marijuana and schizophrenia - which can equally well be explained by schizophrenia leading to an attempt to self-medicate with marijuana, or by a common factor that leads to both marijuana use and schizophrenia.
"But here's the conundrum: while marijuana went from being a secret shared by a small community of hepcats and beatniks in the 1940s and '50s to a rite of passage for some 70% of youth by the turn of the century, rates of schizophrenia in the U.S. have remained flat, or possibly declined. For as long as it has been tracked, schizophrenia has been found to affect about 1% of the population." (http://www.time.com/time/health/article/0,8599,2005559,00.html)
You are wrong, there have been definitive studies that show both, a decreased IQ of up to 8 points in marijuana users under 21
Where did I deny that? My question is whether any such study has even been done for alcohol.
and at least 2% of the heavy marijuana users developing schizophrenia.
Post a link to this alleged study. Then explain why although marijuana use went up, rates of schizophrenia in the U.S. have remained flat.
It’s true that studies show a decreased use of marijuana among adults, but the sad part is that the same studies indicate a big increase in marijuana use among teenagers. Legalizing the drugs will not keep them out of the hands of teenagers.
The available evidence is against you - teens report that they can get illegal-for-adults pot more easily than legal-for-adults beer or cigarettes.
My guess is that if there was any indication of a link between decreased IQ or schizophrenia and alcohol use, there would have been a study. Heck, my grandmother was president of her local WCTU for 20 years, I can assure you they would have done a study if there was any suggestion of a connection.
You are probably too young to know what the WCTU was. It stands for the Women’s Christian Temperance Union.
By the way, the release of the study, showing the link between cannabis and schizophrenia, has been called the “tobacco moment for marijuana”, meaning that there now no longer possible to claim that marijuana is harmless.
